'O'I-L BURNER. I

Application filed september 2,1924. Serial No. 735,335.

To all whom mag concern I Be it known that I, 'PIIERBER-T BARCROFT 'ODELL, a citizen of the United States. of America, residing in the city of Toronto, county of York, Province of Ontario, Canada, have invented certain newj and .useful Improvements in Oil Burners, of. whichthe following is a specification' r N y invention relates to improvementsqin oil burners, and one object of my invention is to provide a contrivanfce of the class set forth especially adapted for, domestic use to be automatic in its action in regulating the pressure of the steam jet so as .torautomat- .ically control the heat generated by the burner, and so make it safe for use.

other object of myinvention is to prevent the fuel passing out of the-oil nozzle when the burner is not in operation and in the following specification I shall describe and illustrate my invention, and what I claim as new will be set forth in the claims forming part of this specification. v

Fig. 1 is a side elevation of my oil burner showing the pipes or conduitsv for the liquids and fluids used. Fig. 2 is an elevation. of the left-hand end of the contrivance, show- Fig.

to receive theair and steam and oil, and which head supports the nozzles. Fig. 4 is a plan View of said distributing head, partly shown in section, and Fig. 5 is a vertical cross section on the line 55, Fig. 4.

In the drawings, like characters of reference refer to the same parts.

2 is a hollow conical shaped steam generator provided'with a central passage-way .3 therethrough. This passage-way widens out from its intake end to its discharge end so that certain well-known advantages will beobtained. Since the discharge end .of the said passageway is wider than the intake end, the flame will be uniformly distributed over the flame zone and consequently no one port on. f, a y ody-aga s which the fl m plays will be overheated. Another advantage obtained is that the noise of combustion is reduced to a minimum, thus removing one of the objections the general public has to appliances of this class.

Water is preferably supplied to said steam generator by gravity by a tank (not shown), and the pipe 4 leads from said tank and communicates with the interior of said steam generator. Any suitable control valve 5 is .tributing head 8.

provided to regulate the volume of Walter passing through the pipe 4.. By means of the pipe 6 steam is piped from the generator 2 into the passage-way 7; formed inithedis- The passageway 7 coinmunicates with a passage-way 9v in the outer end of which is'supported the fluidgnozz-le 10. v

11 is a fuel-levcl-control bowl which con1 municates, by the pipe 12 with a fuel tank (not shown). 13 is a pipe leading fronithe bowl 11 to a port 14: formed in one side ofthe head 8. This port communicates with a passage-way 15 formedinthe foot 16 of said head, and carried by said foot is the vertically-disposed oilnozzle 17 which co1nniunicates with said passage-way '15 18 is a pipe which leads touan air pump, (not shown), and at this point I should make mention that since the air is used only temporarily in this ,contrivance while. starting it, a hand-operated air pump is preferablyzused.

The pipe 18 is coupled to a pipe 19, which pipe. is coupled to the head 8 and. comma nicates with a passage-way 20 formed in said head. The said passage-way 20 communicates with the passage-way 9 which is in communication with the fluid nozzle 10.

Associated with the pipes 18 and 19 is a safety valve diagrammatically indicated at 21, and 22 is a weighted lever pivoted at 2 3, and co-operating with the said safety valve to control pressure of both air and steam. I

When the valve 24 is opened, the fuel oil will flow through the pipe 13 and port 14, and after filling the passage-way '15 it will rise almost to the top. of the oil nozzle 17. Now as before-stated air is used temporarily to start the contriva-nce, and consequent ly thestream of air blowing across the outer end of the nozzle 17 will carry the oil, out of said nozzle and atomize it. The mixtune is then ignited by a flame, and burns. The .said burning mixture will indue course heat the steam generator 2 and generate steam. The steam will then pass through the pipe 6 and into the passage-ways 7 and 9 and escape through the nozzle 10 and perform the function performed by the air.

Obviously it will not be necessary to use air after the steam has been generated.

It is desirous that the pressure of the steam be kept quite low, say approximately, two pounds to the square inch for domestic use, and consequently I provide the safety valve before-mentioned which will blow off in case the pressure goes above the desired amount. Since air is initially passed through the pipe 19, and since this pipe communicates with the passage-ways 20 and 9: and further since the steam passageway 7 communicates with said passage-ways, it is evident that the pipe 19 is bi-functional, because while it conveys air initially to the oil burner, it performs the additional function of an exhaust for the steam when the same reaches an excessive pressure, and therefore it is necessary that a suitable safety valve, such as diagrammatically inclicated at 21, be associated with said pipe 19.

Integrally formed with the head 8 is a pan (2: which surrounds the foot 16. This pan will collect any unconsumed oil that may possibly escape from the nozzle 17, and consequently when this oil is ignited, the heat generated thereby will assist to keep the nozzles hot.

A removable cover Z) to house the space separating the intake end of the steam generator 2 from the head 8 is provided, and in Fig. 1 it is shown clearly that one end of this cover rests upon the generator 2 and the other end rests upon the head 8.

This cover is readily removable to permit the cleaning of the nozzles.

The discharge ends of the nozzles 10 and 17 are preferably located as shown in the drawings so that the stream of air or steam passing through the nozzle 10 will blow directly over the discharge end of the nozzle 17.

Where this contrivance is used for domestic purposes, it is advisable to have the safety valve for the steam, though it must be clearly understood that I may omit this safety valve when my contrivan'ce is used by skilled operators.

Obviously various changes in details of construction may be made without departing from the spirit of my invention.

What I claim is:

1. In a contrivance of the class described, in combination a chambered steam generator having a passage-way therethrough; a distributing head located in front of said steam generator and provided in its upper portion with distinct inlet passage-ways which meet in a common horizontally-disposed outlet passage-way; a fluid nozzle mounted in said last-mentionedpassageway and projecting beyond said head and opening towards the passage-way through said generator; a foot integrally formed with said distributing head and provided with a fuel passage-way therethrough, which communicates with an intake fuel passage-way formed in said head; a vertically-disposed fuel nozzle carried by said foot and opening into the fuel passage-way thereof, and having its discharge end located adjacent the discharge end of said fluid nozzle; an air pipe opening into one of said first-mentioned inlet passage-ways; a. safety valve associated with said air pipe; a steam pipe leading from said steam generator and opening into the other of said first-mentioned inlet passage-ways, the excessive pressure of steam escaping through said air pipe, and a fuel-level-control bowl coupled to the fuel intake of said head, the whole arranged to operate as set forth.
